Method and apparatus for port access management at a distributed job manager in a digital multi-processor system

A method for port management access at a distributed job manager, comprising:

• initializing a port access process for each of one or more ports on a processing device;
• determining first whether a job is assigned to an active slot identified by an active_slot_id on the processing device, and when the determining is positive then:
• determining second whether the job has been serviced by a port identified by the active_slot_id;
• and when either the first determining is negative or the second determining is positive then:
• retesting the first and second determining;
• else:
• determining whether the job requires an access to the port identified by the active_slot_id;
• and when the determining is positive then:
• fetching the port's configuration words;
• processing the fetched port's configuration words;
• marking the job as serviced by the port upon conclusion or the processing of the fetched port's configuration words;
• and
• recalculating the value of the active_slot_id.

A non-transitory computer readable medium comprising:

• a plurality of executable instructions that when executed by at least one processor of an apparatus for port access management at a distributed job manager cause the apparatus system to:
• initialize a port access process for each of one or more ports on a processing device;
• determine first whether a job is assigned to an active slot identified by an next active_slot_id on the processing device, and when the determining is positive then:
• determine second whether the job has been serviced by a port identified by the active_slot_id;
• and when either the first determining is negative or the second determining is positive then:
• retest the first and second determining;
• else:
• determine whether the job requires an access to the port identified by the active_slot_id;
• and when the determining is positive then:
• fetch the port's configuration words;
• process the fetched port's configuration words;
• mark the job as serviced by the port upon conclusion or the processing of the fetched port's configuration words;
• and
• recalculate the value of the active_slot_id.
